[0034] 探头22例如由钛合金等金属材料形成。 [0034] The probe 22 is formed from a metal material such as titanium and the like. 探头22的材质并不限定于钛合金,例如也可以是硬铝等其他金属材料。 Probe material 22 is not limited to titanium, for example, it may be a hard material such as aluminum other metals.

[0035] 如图3所示,探头22沿着长度轴线C延伸。 [0035] As shown in Figure 3, the probe 22 extends along the length axis C. 探头22包括上述探头顶端面43和探头外周部44。 Probe 43 and the probe 22 includes an outer peripheral portion of the probe tip surface 44. 在探头外周部44的基端部设有与变幅杆27的内螺纹部33螺纹接合的外螺纹部45。 In the probe outer circumferential portion of the base end portion 44 is provided with an external thread portion 27 of the horn and the internally threaded portion 33 of screw 45 engages. 通过外螺纹部45与内螺纹部33螺纹接合,从而探头22安装于变幅杆27的顶端方向侧。 Externally threaded section 45 and the internally threaded portion 33 threaded engagement, so the direction of the probe 22 is mounted on the top side 27 of the horn through. 在探头22安装于变幅杆27的状态下,由超声波振子26产生的超声波振动经由变幅杆27、探头22传递至探头顶端面43。 In a state probe 22 attached to the horn 27, ultrasonic vibration generated by the ultrasonic transducer 26 via the horn 27, the probe 22 is transmitted to the probe tip surface 43. 通过向探头顶端面43传递超声波振动,并且进行上述送液,从而利用气蚀现象进行探头顶端面43上的生物体组织的破碎、乳化。 43 transmitting ultrasonic vibration to the probe tip surface, and the above-mentioned liquid feed to take advantage of the phenomenon of cavitation tip of the probe on the surface of the living tissue of 43 broken emulsion through. 通过气蚀现象,血管等弹性较高的组织不会被破碎,肝细胞等没有弹性的生物体组织被选择性地破碎、乳化。 By cavitation, more elastic blood vessels and other tissues will not be broken, and liver cells do not elastic body tissue is selectively broken emulsion.

[0036] 另外,设定探头22、超声波振子26及变幅杆27的连结体的沿着长度轴线C的长度,以成为探头22的探头顶端面43成为超声波振动的波腹位置、并且超声波振子26的基端成为超声波振动的波腹位置的状态。 [0036] In addition, setting the probe 22, the ultrasonic transducer 26 and horn 27 of the connecting member along the length of axis C, in order to become the top surface of the probe 22 of the probe 43 becomes an antinode position of ultrasonic vibrations, and the ultrasonic transducer the base end 26 of the ultrasonic vibration antinode become position. 由于探头顶端面43成为超声波振动的波腹位置,因此更高效地产生气蚀。 As the probe tip surface 43 to become the ultrasonic vibration antinode position, and therefore more efficient real estate angry eclipse. 另外,超声波振动是振动的传递方向与振动方向平行的纵向振动,振动的传递方向和振动方向与长度轴线C平行。 Further, ultrasonic vibration of longitudinal vibration transmission direction parallel to the direction of vibration, the vibration of the vibration transmission direction and C direction parallel to the longitudinal axis. 另外,利用探头22和变幅杆27构成用于从基端方向朝向顶端方向传递超声波振子26的超声波振动的振动传递部。 Further, the use of probe 22 and horn 27 for constituting the vibration transmitting portion toward the distal direction from the proximal end of the transfer direction of the ultrasonic transducer 26 of the ultrasonic vibration.

[0038] 如图7所示,在内部空间52内设有管单元24。 [0038] As shown in Figure 7, the inner space 52 features a tube unit 24. 管单元24具有沿着长度轴线C设置的第I管55和夹设在探头22的空间限定面53 (内表面)与第I管55的外周面之间的第I间隔件56。 Pipe unit 24 includes a first tube 55 and sandwiched I space probe 22 defines surface 53 (inner surface) and I of the outer peripheral surface of the tube 55 is disposed along the longitudinal axis of the first I C between the spacer 56. 在第I管55的内侧公开有供利用气蚀现象破碎、乳化的生物体组织、输送的液体等抽吸对象通过的抽吸路径。 I inside the first tube 55 is disclosed for use cavitation broken suction path emulsified living tissue, the object conveyed by the suction of liquids.

[0039] 第I管55例如利用PTFE等合成树脂材料形成为细长的圆筒形。 [0039] I of the tube 55 using, for example a synthetic resin material such as PTFE is formed into an elongated cylindrical shape. 因此,第I管55的内周面具有比探头22的空间限定面53低的摩擦性(高的滑动性)。 Therefore, I, the inner circumferential surface 55 of the tube than the limited 53 space probe 22 low friction surface (high slip resistance). 另外,第I管55具有比探头22低的导热性。 Further, the first pipe 55 I have a low thermal conductivity than the probe 22. 在第I管55的内周侧设有供被抽吸的生物体组织等抽吸对象朝向基端方向通过的通路部58。 I of the inner peripheral side tube 55 is provided for the living tissue and the like is drawn in the proximal direction toward the target suction passage portion 58 through. 第I管55在顶端方向侧和与探头22的两个开口部54相连通的内部空间52液密地连接。 I pipe 55 at the top of the first direction side and two openings 54 and the probe 22 is connected through an internal space 52 fluid-tightly connected. 具体地说,如图4所示,第I管55的顶端方向侧的端部利用粘接剂等粘接于自探头22设于内部的台阶部29。 Specifically, as shown in FIG. 4, the first end portion of the tube distal direction I side 55 using adhesive or the like is bonded to the probe from the stepped portion 22 provided in the interior 29. 同样地,第I管55的基端方向的端部与顶端方向的端部相同地利用粘接剂等粘接于设于变幅杆27的空洞部34的内部的台阶部。 Utilizing the same manner as with the tip end direction of the end portion in the same manner, the first tube in the proximal direction I of the adhesive 55 is bonded to the inside of the stepped portion provided in the horn portion 27 of the cavity 34. 另外,第I管55在基端方向上连接于变幅杆27的空洞部34,但是也可以直接连接于抽吸管35。 In addition, Article I pipe 55 in the proximal direction is connected to the horn 27 of the cavity 34, but can also be directly connected to the suction pipe 35. 第I管55也可以构成为能够经由探头22的基端侧的开口部分57 (参照图3)相对于探头22的内部空间52进行拆装。 I, tube 55 may be configured to be open through the base end side portion 57 of the probe 22 (see FIG. 3) with respect to the internal space 52 of the probe 22 be removable. 同样地,第I管55也可以构成为能够相对于变幅杆27的空洞部34进行拆装。 Similarly, the first I tube 55 may be configured with respect to the hollow portion 34 horn 27 is removable.

[0040] 第I间隔件56(内衬)例如包括PTFE(聚四氟乙烯)等合成树脂材料。 [0040] I of the spacer 56 (liner) including, for example PTFE (polytetrafluoroethylene), and other synthetic resin materials. 因此,第I间隔件56具有比探头22低的导热性。 Therefore, the first spacer 56 I probe 22 having a lower thermal conductivity than that. 第I间隔件56在本实施方式中形成为包围第I管55的筒状(圆筒形状)。 I, the spacer 56 is formed so as to surround the first cylindrical tube 55 I (cylindrical shape) in the present embodiment. 第I间隔件56将第I管55支承为第I管55的外周面不接触空间限定面53 (内表面)的状态。 I, I of the spacer 56 to the support tube 55 I of the outer peripheral surface of the tube 55 does not contact the surface 53 defining the space (inner surface) of the state.

[0041] 第I间隔件56在长度轴线方向上设置在与具有由超声波振子26产生的超声波振动的一个波节位置A对应的位置。 [0041] Article I of the spacer 56 in the longitudinal direction is provided in a nodal position A corresponding position with the ultrasonic vibrations generated by the ultrasonic transducer 26's. S卩,第I间隔件56的长度轴线C方向的长度比探头22的长度轴线C方向的全长短。 S Jie, Section I of the spacer length direction of the axis C 56 C axis length than the length direction of the whole length of the probe 22. 另外,在振幅为零的(即,不振动的)超声波振动的波节位置,由超声波振动引起的应力变大。 Further, the amplitude is zero (i.e., no vibration) node position of ultrasonic vibration, ultrasonic vibration caused by the stress becomes large. 因此,在超声波振动的波节位置,由于形成探头的金属的内部摩擦而产生了热量。 Thus, in the ultrasonic vibration node position, due to the formation of the internal friction of a metal probe to generate heat.

[0042] 接着,说明本实施方式的超声波处理装置11的作用。 [0042] Next, the effect of the ultrasonic treatment apparatus 11 of the present embodiment. 在使用超声波处理装置11进行生物体组织的超声波抽吸时,利用输入单元16中的操作等,从超声波控制部31经由电信号线32向超声波振子26供给电流。 When using the ultrasonic treatment apparatus 11 of the ultrasonic aspiration living tissue, using the input operation unit 16, an ultrasonic control unit 31 to the current 26 supplied from the ultrasonic transducer 32 via the signal line. 由此,超声波振子26产生超声波振动。 Thereby, the ultrasonic transducer 26 generates ultrasonic vibration. 然后,向探头22的探头顶端面43传递超声波振动。 Then, 43 transmitting ultrasonic vibration to the probe tip of the probe surface 22. 另外,利用送液单元15,经由间隙41向生物体组织输送生理盐水等液体。 In addition, the use of liquid-feeding unit 15, delivery of saline and other liquid through the gap 41 to the living tissue. 通过向探头顶端面43传递超声波振动,并且进行送液,从而产生气蚀。 43 transmitting ultrasonic vibration to the probe tip face, and were sent to liquid, thereby generating cavitation by. 在气蚀作用下,肝细胞等弹性较低的生物体组织被选择性地破碎,并作为处理片(生物体组织片)被切除(去除)。 In the cavitation effect, less elastic body tissue liver cells are selectively broken, and as a treatment sheet (living tissue slices) are cut off (removed). 此时,在探头22的波节位置A,由于由超声波振动引起的内部摩擦而以高温进行发热。 In this case, the position of the probe node A 22, and due to internal friction caused by the ultrasonic vibration and heat to a high temperature.

[0043] 抽吸单元14使负压作用于包括第I管55、空洞部34以及抽吸管35的抽吸路径,并经由开口部54对被切除的抽吸对象(处理片)进行抽吸。 [0043] the negative pressure suction unit 14 includes a first I applied to pipe 55, the suction path of the cavity 34 and the suction tube 35 and through the opening 54 pairs were excised drawn objects (processing film) suction . 抽吸对象经由第I管55、空洞部34、抽吸管35的内部被抽吸并回收至抽吸单元14。 Object suction pipe 55 via the first I, cavity 34, suction inside the suction pipe 35 is sucked to the suction unit 14 and recovered. 此时,抽吸对象(处理片)不直接接触发热的探头22,而是经由第I管55的内侧被回收。 In this case, the suction objects (processing film) is not in direct contact with heat probe 22, but the inside of the tube 55 via the first I is recovered.

[0044] 根据第I实施方式,超声波处理装置11包括:振动传递部,其沿着长度轴线C延伸设置,并从基端方向向顶端方向传递超声波振动;空间限定面53(内表面),其在振动传递部的内部沿着长度轴线C限定内部空间52 ;第I管55,其在内部空间52内沿着长度轴线C延伸设置;通路部58,其设于第I管55的内周侧,供被抽吸的抽吸对象朝向基端方向通过;以及第I间隔件,其在与所述长度轴线平行的长度轴线方向上的、所述超声波振动的某波节位置夹设在所述空间限定面与所述第I管之间,并将所述第I管支承为所述第I管的外周面不接触所述空间限定面的状态。 [0044] According to embodiment I, the ultrasonic treatment apparatus 11 comprising: a vibration transmitting portion, which extends along the length of the axis C set, and transmitting ultrasonic vibration from the proximal end toward the distal end direction; space defining surface 53 (inner surface), which within the vibration transmitting portion defining an axis C along the length of the internal space 52; I, tube 55, which extends within the interior space 52 disposed along the longitudinal axis C; passage portion 58, provided on the inner circumferential side of the tube 55 I for a suction is drawn toward the base end direction by the object; and I of the spacer, which in the longitudinal direction parallel to the longitudinal axis, the position of a node of the ultrasonic vibrations is interposed in the the space defined between the surface and the first tube I, and I said first tube supporting an outer peripheral surface of the first I tube does not contact the space defined surface state.

[0045] 一般来说,在超声波处理装置11中,在探头22中的相当于超声波振动的波节位置A的位置,虽不产生振动,但是由于内部摩擦等而成为高温。 [0045] In general, in the ultrasonic treatment apparatus 11, 22 in a position corresponding to the ultrasonic vibration node position A of the probe, though not vibrate, but due to internal friction and a high temperature. 另一方面,由于在超声波振动的波节位置A不引起振动,因此在内部空间52中流动的处理片易于在相当于该波节位置A的部分蓄积。 On the other hand, since the ultrasonic vibration node position A does not cause vibrations, and therefore the inner space 52 in the process flow sheet is easy to position corresponding to the node A portion of the accumulation. 而且,在以往的结构中,如此蓄积的处理片有时凝固并附着于高温的探头22的空间限定面53,有时后续的处理片蓄积于该附着的处理片,从而在内部空间52内产生堵塞。 Further, in the conventional structure, thus treated sheets accumulated and solidified is sometimes attached to the high temperature of the space defining surface 53 of the probe 22, and sometimes the subsequent processing of the sheet accumulated in the disposal sheet is attached, thereby clogging within the interior space 52.

[0046] 根据上述结构,在处理片与探头22的空间限定面53之间夹设有第I管55和第I间隔件56,第I管55隔着第I间隔件56与探头22相接触。 [0046] According to the above configuration, the probe 22 and the spatial processing sheet defines a folder provided with a first pipe I 55 and I 56 between the surface of the spacer 53, the first tube 55 via a first I I spacer 56 in contact with the probe 22 . 因此,在超声波振动的波节位置A,即使在探头22成为高温的情况下,也能够使将波节位置A的热量向第I管55传递的效率变差(即,难以引起向第I管55的热传递)。 Therefore, the ultrasonic vibration node position A, even at a high temperature in the case of the probe 22, it is possible to make the heat node position A to I of the tube 55 deteriorates transfer efficiency (i.e., it is difficult to cause the tube to the first I 55 heat transfer).

[0047] 另外,第I间隔件56和第I管55的导热性比探头22的导热性低。 [0047] In addition, Section I of the spacer tube 56 and I 55 is lower than the thermal conductivity thermal conductivity probe 22. 因此,难以引起热量向第I管55的移动,能够防止处理片的凝固以及凝固的处理片向第I管55的附着。 Therefore, it is difficult to cause the heat pipe to the first mobile I 55, it is possible to prevent coagulation and solidification of the sheet processing to the sheet processing I of the tube 55 is attached.

[0048] 而且,第I管55的内表面的滑动性比探头22的空间限定面53 (内表面)的滑动性高。 [0048] Moreover, Part I of the inner surface of the sliding tube 55 of the probe 22 than the space defining surface 53 (inner surface) of the sliding resistance is high. 根据该结构,能够有效地防止处理片向第I管55的附着以及附着后产生的第I管55的堵塞。 According to this structure, it is possible to effectively prevent the disposal sheet is attached to the first tube 55 and I I of tube blockage produced after attachment 55. 第I管55能够从探头22的内部空间52内进行拆装,因此即使产生了堵塞,也能够通过更换第I管55而迅速地再次使用超声波处理装置11。 The first tube 55 can be detachably I from the interior space 22 of the probe 52, and therefore even if the clogging, it is possible by replacing the first tube 55 and I quickly using an ultrasonic treatment apparatus 11 again.

[0049] 参照图9,说明第I实施方式的超声波处理装置11的变形例。 [0049] Referring to FIG. 9, a modification of the ultrasonic treatment apparatus 11 of the first embodiment of I. 在该变形例中,第I间隔件56的形状并不是像上述第I实施方式那样为筒状,而是如图9所示,在用与长度轴线C交叉(正交)的面剖切探头22得到的截面上不连续地形成(即,在第I管55的圆周方向上不连续地形成。)。 In this modification, the spacer I, 56 I shaped not like the first embodiment as a cylindrical shape, but as shown, with the longitudinal axis C intersecting (orthogonal) of the surface of the cut probe 9 22 is discontinuously formed on the obtained cross section (i.e., in the circumferential direction of the first tube 55 I discontinuously formed.). 也能够说第I间隔件56在绕长度轴线C的方向上的一部分范围内与第I管55的外周部相抵接。 It is possible to say that a portion of the outer periphery of the range I, about the length of the spacer 56 in the direction of the axis C of the first I tube 55 abut.

[0050] 在该变形例中,第I间隔件56例如分离(分割)设于第I管55的上侧、下侧、右侦I左侧这4个位置。 [0050] In this modification, the first I spacer 56, for example separation (split) provided on the upper side of the first I managed 55, lower side, left side and right I detect these four locations. 因此,能够减小用与长度轴线C交叉的面剖切第I间隔件56得到的截面的面积(截面积)。 Thus, it is possible to reduce the longitudinal axis C intersecting with the surface area of the cross section taken along section I obtained spacer 56 (cross-sectional area). 由此,在超声波振动的波节位置A,即使在探头22成为高温的情况下,也能够使波节位置A的热量向第I管55传递的效率变差(即,难以引起向第I管55的热传递)。 Thereby, the ultrasonic vibration node position A, even in the case where a high temperature probe 22, it is possible to make the node position A of the heat transfer tube 55 to the first I efficiency is deteriorated (i.e., it is difficult to cause the tube to the first I 55 heat transfer). 由此,能够进一步有效地防止处理片的凝固以及凝固了的处理片向第I管55的附着。 Thereby, it is possible to further effectively prevent the coagulation and solidification of the sheet processing to the sheet processing I of the tube 55 is attached. 另外,作为第I间隔件56的设置方法,并不限定于上述,也可以分离(分割)配置于6个位置或8个位置。 Further, as the spacer member is provided a method I 56 is not limited to the above and to be separated (split) disposed at positions 6 or 8 positions.

[0056] 在第I管55的内周面与第2管61的外周面之间设有在第I管55与第2管61之间实质上作为隔热材料发挥作用的第2间隙63 (空气层、间隙)。 [0056] I between the first tube 55 and the inner circumferential surface of the outer circumferential surface of the second pipe 61 is provided between the first tube 55 and the second I 2 61 substantially functioning as a heat insulating material of the second gap 63 ( an air layer, gap).

[0057] 接着,说明本实施方式的超声波处理装置11的作用。 [0057] Next, the role of the ultrasonic treatment apparatus of the present embodiment 11. 若进行输入单元16中的操作等,则向超声波振子26供给电流,超声波振子26产生超声波振动。 If the input operation unit 16, the ultrasonic transducer 26 is supplied to the current, the ultrasonic transducer 26 generates ultrasonic vibration. 然后,向探头22的探头顶端面43传递超声波振动。 Then, 43 transmitting ultrasonic vibration to the probe tip of the probe surface 22. 另外,利用送液单元15向生物体组织输送生理盐水等液体。 In addition, the use of liquid-feeding unit 15 to the living body tissue conveying liquid such as physiological saline. 在探头顶端面43上产生气蚀,弹性较低的生物体组织被选择性地破碎,并作为处理片(生物体组织片)被切除。 Cavitation on the surface of the probe tip 43, less elastic body tissue is selectively broken, and as a treatment sheet (living tissue sheet) is removed. 此时,在探头22的波节位置A,由于超声波振动的内部摩擦而以高温进行发热。 In this case, the position of the probe node A 22, the ultrasonic vibrations due to internal friction and heat to a high temperature.

[0058] 抽吸单元14使负压作用于包括第2管61、空洞部34以及抽吸管35的抽吸路径,并经由开口部54对被切除的抽吸对象(处理片)进行抽吸。 [0058] The effect of the negative pressure suction unit 14 includes a suction path in the first two 61, the cavity 34 and the suction tube 35 and through the opening 54 pairs were excised drawn objects (processing film) suction . 抽吸对象经由第2管61、空洞部34、抽吸管35的内部被抽吸并回收至抽吸单元14。 The suction through the first two objects 61, cavity 34, suction inside the suction pipe 35 is sucked to the suction unit 14 and recovered. 此时,抽吸对象(处理片)不直接接触发热的探头22,而是经由第2管61的内侧被回收,因此防止处理片(生物体组织片)向探头22的空间限定面53的附着。 In this case, the suction objects (processing film) is not in direct contact with heat probe 22, but is recovered via the inside of the second tube 61, thus preventing the disposal sheet (living tissue sheet) into the space defined probe 22 attached to surface 53 .

[0059] 根据本实施方式,超声波处理装置11还包括在第I管55的内周侧沿着长度轴线C延伸设置、并在内部形成有通路部58的第2管61。 [0059] According to the present embodiment, the ultrasonic treatment apparatus 11 further includes an inner peripheral side I of the tube 55 extending along the length of the axis C, and is formed with a second passage portion 58 of the pipe 61 in the interior. 根据该结构,由于在第I管55的内侧还设有第2管61,因此能够使探头22侧的热量进一步难以传递到第2管61。 According to this structure, since the inside I of the tube 55 is also provided with a second pipe 61, it is possible to further heat the probe 22 side is hardly transmitted to the second pipe 61. 由此,能够防止处理片附着于第2管61,从而能够防止在第2管61内形成堵塞的起点。 Thereby, it is possible to prevent the disposal sheet 61 is attached to the first two, it is possible to prevent the starting point in the first two 61 formed clogging. 另外,当在第I管55与第2管61之间设有第2间隙63 (空气层)时,该第2间隙63实质上作为隔热材料发挥作用,因此能够使第I管55侧的热量难以传递到第2管61侧。 In addition, when I first tube 55 between the first two and has a 61 second gap 63 (air layer), the second gap 63 substantially as the insulation materials play a role, so I can make the first tube 55 side heat is hardly conducted to the first two 61 side. 由此也能够防止处理片向第2管61的粘贴。 Thus it is possible to prevent processing of sheet 61 to the first two of the paste.

[0060] 第2管61的导热性比探头22的导热性低。 [0060] The first two 61 thermal conductivity is lower than thermal conductivity probe 22. 因此,难以引起热量向第2管61的移动,能够防止处理片的凝固以及凝固了的处理片向第2管61的附着。 Therefore, it is difficult to cause the second heat pipe 61 to the mobile, it is possible to prevent coagulation and solidification of the sheet processing to the sheet processing section 61 is attached to two.

[0061] 另外,第2管61的内表面的滑动性比探头22的空间限定面53的滑动性高。 [0061] Further, the sliding resistance of the inner surface of the second pipe 61 than the space of the probe 22 of the sliding surface 53 is defined high. 根据该结构,能够有效地防止处理片的凝固以及凝固了的处理片向第2管61的附着。 According to this structure, it is possible to effectively prevent the coagulation and solidification of the sheet processing to the sheet processing section 61 is attached to two. 第2管61能够从探头22的内部空间52内进行拆装,因此即使产生了堵塞,也能够通过更换第2管61而迅速地再次使用超声波处理装置11。 The first two 61 can be detachably from the interior space 22 of the probe 52, and therefore even if the clogging, it is possible by replacing the first two 61 and quickly re-use an ultrasonic treatment apparatus 11.

[0062](第3实施方式) [0062] (third embodiment)

[0063] 接着,参照图11说明本发明的第3实施方式。 [0063] Next, referring to FIG. 11 illustrates a third embodiment of the present invention. 第3实施方式的超声波处理装置11是将第2实施方式的结构如下变形后的超声波处理装置。 Ultrasonic treatment apparatus 11 of the third embodiment is the configuration of the second embodiment is described below deformed ultrasonic treatment apparatus. 另外,主要说明与第2实施方式不同的部分,对与第2实施方式相同的部分省略说明。 In addition, the main description of the second embodiment, different parts, with the second embodiment of the same portions will be omitted.

[0064] 如图11所示,在探头22的内部空间52内设有管单元24。 [0064] 11, the interior space 22 of the probe 52 features a tube unit 24. 管单元24具有:沿着长度轴线C设置的第I管55、夹设在探头22的空间限定面53 (内表面)与第I管55之间的第I间隔件56、设于第I管55的内侧的第2管61以及夹设在第I管55与第2管61之间的第2间隔件64。 Tube unit 24 has: C disposed along the longitudinal axis I of the tube 55, the probe 22 is interposed in the space defined surface 53 (inner surface) of the first tube 55 between I I of the spacer 56, provided on the first tube I the inside of the first two 55 and 61 interposed in the first pipe I 55 and the second spacer 61 between the first two 64. 第I管55、第I间隔件56以及第2管61的结构与第I实施方式和第2实施方式相同。 The first tube 55 I, I, the spacer 56 and the same structure of the second pipe 61 and the first I mode embodiment and the second embodiment.

[0065] 在第I管55的内周面与第2管61的外周面之间设有在第I管55与第2管61之间实质上作为隔热材料发挥作用的第2间隙63(空气层、间隙)。 [0065] I between the first tube 55 and the inner circumferential surface of the outer circumferential surface of the second pipe 61 is provided between the first tube 55 and the second I 2 61 substantially functioning as a heat insulating material of the second gap 63 ( an air layer, gap). 另外,在本实施方式中,由于在第I管55与第2管61之间夹设有第2间隔件64,因此即使在探头22处于任意设置角度(使用角度)的情况下,也始终确保有恒定大小的第2间隙63。 Further, in the present embodiment, since the first I tube clamp 64 is provided between the second spacer member 55 and the second tube 61, and therefore even when the probe 22 is set at an arbitrary angle (using an angle) of a case, always make sure There second gap 63 of constant size.

[0066] 第2间隔件64(第2内衬)夹设在第I管55的外周面与第2管61的内周面之间。 [0066] the second spacer 64 (the second liner) interposed between the inner peripheral surface I of the tube 55 and the outer peripheral surface 61 of the first two. 第2间隔件64将第2管61支承为第2管61的外周面不接触第I管55的内周面的状态。 64 of the second spacer 61 supporting the first two for the first two 61 does not contact the outer circumferential surface of the first state I the inner circumferential surface of the tube 55. 第2间隔件64例如包括PTFE(聚四氟乙烯)等合成树脂材料。 A second spacer 64 includes, for example PTFE (polytetrafluoroethylene) or the like of a synthetic resin material. 因此,第2间隔件64具有比探头22低的导热性。 Thus, the second spacer 64 having a low thermal conductivity than the probe 22.

[0067] 第2间隔件64形成为包围第I管55的筒状(圆筒形状)。 [0067] the second spacer 64 is formed so as to surround the first cylindrical tube 55 I (cylindrical shape). 第2间隔件64在长度轴线C方向上设置在自利用超声波振子26产生的超声波振动的波节位置A离开的位置(偏离的位置),例如,在之间夹着波节位置A的两侧设有一对。 , E.g., on both sides of the second spacer 64 in the longitudinal direction of the axis C disposed at a position (position deviation) by ultrasonic vibration from the ultrasonic transducer 26 generates a node interposed between the position A away from the node A in position There is a right. 另外,第2间隔件64能够也说是设置在利用超声波振子26产生的超声波振动的波腹位置B。 Further, the second spacer 64 can also be said to be provided in the use of ultrasonic vibration generated by the ultrasonic transducer 26 antinode position B. 另外,第2间隔件64的数量并不限定于两个。 Further, the number of the second spacer 64 is not limited to two. 第2间隔件64也可以在自超声波振动的波节位置A偏离的位置设有例如多个,在该情况下,优选的是,在第2间隔件64彼此之间设置恒定的间隔。 A second spacer 64 may be provided with a plurality of nodes such as a position offset from the position A of the ultrasonic vibrations, in this case, it is preferable that the second spacer 64 disposed between each constant interval. 另外,第2间隔件64也可以构成为能够经由探头22的基端侧的开口部分57相对于探头22的内部空间进行拆装。 Further, the second spacer 64 may be configured to be open through the base end side portion 57 of the probe 22 relative to the inner space of the probe 22 is removable.

[0068] 在本实施方式中,第I间隔件56的长度轴线方向上的第I轴线平行尺寸LI小于第2间隔件64的长度轴线方向上的第2轴线平行尺寸L2。 [0068] In the present embodiment, the spacer I, the first I axial length dimension parallel to the axis 56 on a second axis parallel to the LI is less than the length dimension L2 in the axial direction of the second member 64 on the spacer.

[0069] 接着,说明本实施方式的超声波处理装置的作用。 [0069] Next, the effect of the present embodiment is an ultrasonic treatment apparatus. 若进行输入单元16中的操作等,则向超声波振子26供给电流,超声波振子26产生超声波振动。 If the input operation unit 16, the ultrasonic transducer 26 is supplied to the current, the ultrasonic transducer 26 generates ultrasonic vibration. 然后,向探头22的探头顶端面43传递超声波振动。 Then, 43 transmitting ultrasonic vibration to the probe tip of the probe surface 22. 另外,利用送液单元15向生物体组织输送生理盐水等液体。 In addition, the use of liquid-feeding unit 15 to the living body tissue conveying liquid such as physiological saline. 在探头顶端面43上产生气蚀,弹性较低的生物体组织被选择性地破碎,并作为处理片(生物体组织片)被切除(去除)。 Cavitation on the surface of the probe tip 43, less elastic body tissue is selectively broken, and as a treatment sheet (living tissue slices) are cut off (removed). 此时,探头22的波节位置A由于超声波振动的内部摩擦而成为高温。 In this case, the position of the probe 22 of the node A due to the internal friction of ultrasonic vibrations and a high temperature.

[0070] 抽吸单元14使负压作用于包括第2管61、空洞部34以及抽吸管35的抽吸路径,并经由开口部54对被切除的抽吸对象(处理片)进行抽吸。 [0070] so that negative pressure suction unit 14 includes a suction path in the first two 61, the cavity 34 and the suction tube 35 and through the opening 54 pairs were excised drawn objects (processing film) suction . 抽吸对象经由第2管61、空洞部34、抽吸管35的内部被抽吸并回收至抽吸单元14。 The suction through the first two objects 61, cavity 34, suction inside the suction pipe 35 is sucked to the suction unit 14 and recovered. 此时,抽吸对象(处理片)不直接接触发热的探头22,而是经由第2管61的内侧被回收。 In this case, the suction objects (processing film) is not in direct contact with heat probe 22, but through the inside of the first two 61 are recycled. 另外,由于利用第2间隔件64始终在第I管55与第2管61之间确保有第2间隙63 (空气层),因此第I管55与第2管61不会直接接触,第I管55与第2管61之间的热量的移动成为最小限度。 Further, since the second spacer member 64 is always in the tube between the first 55 and the second I 2 second gap 61 to ensure that there is 63 (air layer), so the first I tube 55 does not directly contact with the first two 61, Part I moving the heat pipes 55 and 61 between the first 2 becomes minimum.

[0071] 根据第3实施方式,超声波处理装置11还包括夹设在第I管55与第2管61之间、并将第2管61支承为第2管61的外周面不接触第I管55的内周面的状态的第2间隔件64。 [0071] According to the third embodiment, the ultrasonic treatment apparatus 11 further comprises interposed between the first two 55 and 61 I of tube 61 and the first support 2 for the first two 61 does not contact the outer circumferential surface of the pipe section I the second inner circumferential surface of the spacer 55 of the 64 states. 根据该结构,与探头22的使用角度无关地始终防止第I管55与第2管61相接触,在第I管55与第2管61之间确保有第2间隙63 (空气层、间隙)。 According to this structure, the use of the probe 22 is always prevented regardless of the angle I of the tube 55 into contact with the second pipe 61, the first tube I to ensure that there is a second gap 63 (air layer, gap) between the first two 55 and 61 . 因此,能够有效地防止由探头22产生的热量经由第I管55向第2管61传递。 Thus, it is possible to effectively prevent the heat generated by the probe 22 via the first tube 55 is transmitted to the first I 2 61. 由此,能够进一步防止抽吸对象(处理片)附着于第2管61而成为第2管的堵塞的起点。 Thereby, it is possible to further prevent the suction objects (processing film) 2 is attached to the first 61 and the starting point for the first two clogging.

[0072] 另外,在本实施方式中,第2间隔件64设置在自超声波振动的波节位置A离开的位置。 [0072] Further, in the present embodiment, the second spacer 64 is provided at a position from the position of the ultrasonic vibration nodes A departure. 根据该结构,即使有时热量经由第I间隔件56、第I管55以及第2间隔件64从探头22向第2管61传递,也能够延长热量到达第2管61的距离。 According to this structure, even if sometimes the heat through the first spacer 56 I, I, 55 and 64 reach the pipe 22 from the probe 61 to the first two passes, it is possible to extend the heat pipe 61 of the second length of the second spacer. 由此,能够迂回地引导探头22侧的热量,能够极力防止热量向第2管61传递。 This makes it possible to guide the roundabout heat probe 22 side, it is possible to prevent heat transfer strongly the first two to 61. 由此,能够防止处理片附着于第2管61的内侧,从而能够防止处理片堵塞第2管61内。 This can prevent the inside processing section 2 is attached to the sheet 61, thereby preventing clogging of the first handle piece 61 2.

[0073] 第2间隔件64的导热性比探头22的导热性低。 [0073] the second spacer 64 is lower than the thermal conductivity thermal conductivity probe 22. 因此,难以引起热量向第2管61的移动,能够防止处理片向第2管61的粘贴。 Therefore, it is difficult to cause the second heat pipe 61 to the mobile, it is possible to prevent the handle 2 to the second sheet 61 pasted.

[0074] 第2管61的内表面的滑动性比探头22的空间限定面53的滑动性高。 [0074] sliding of the inner surface of the second pipe 61 than the space of the probe 22 of the sliding surface 53 is defined high. 根据该结构,能够有效地防止处理片向第2管61的附着。 According to this structure, it is possible to effectively prevent the handle 2 to the second sheet 61 is attached. 第2管61能够从探头22的内部空间52内进行拆装,因此即使产生了堵塞,也能够通过更换第2管61而迅速地再次使用超声波处理装置11。 The first two 61 can be detachably from the interior space 22 of the probe 52, and therefore even if the clogging, it is possible by replacing the first two 61 and quickly re-use an ultrasonic treatment apparatus 11.

[0075] 第I间隔件56的长度轴线C方向上的第I轴线平行尺寸小于第2间隔件64的长度轴线C方向上的第2轴线平行尺寸。 [0075] The I axis parallel dimensions of the spacer length axis C direction on I 56 less than a second dimension parallel to the axis of the second spacer length axis direction of 64 C on. 根据该结构,能够减小第I间隔件56在长度轴线方向上的截面积,在靠近发热源的第I间隔件56中,能够难以引起热量从探头22向第I管55的移动。 According to this structure, the spacer can be reduced I, in the longitudinal direction 56 of the cross-sectional area, the heat source near the first spacer 56 I, can be difficult to cause the heat from the probe 22 to move toward the first tube 55 I.

[0076](第4实施方式) [0076] (fourth embodiment)

[0077] 接着,参照图12说明本发明的第4实施方式。 [0077] Next, with reference to FIG. 12 illustrates a fourth embodiment of the present invention. 第4实施方式的超声波处理装置11是将第I实施方式的结构如下变形后的超声波处理装置。 Ultrasonic treatment apparatus 11 of the fourth embodiment is the structure of the first embodiment is modified as follows I after ultrasonic treatment apparatus. 另外,主要说明与第I实施方式不同的部分,对与第I实施方式相同的部分省略说明。 Further, mainly described in the first embodiment, different parts I, I for the first embodiment and the same parts will be omitted.

[0079] 环构件62例如利用PTFE等合成树脂材料形成为圆筒形。 [0079] ring member 62 using, for example a synthetic resin material such as PTFE is formed into a cylindrical shape. 因此,环构件62具有比探头22的空间限定面53低的摩擦性(高的滑动性)。 Therefore, the ring member 62 has more than 53 space probe 22 defines a low friction surface (high slip resistance). 另外,环构件62具有比探头22低的导热性。 Further, the ring member 62 has a lower thermal conductivity than the probe 22. 环构件62设置在与超声波振动的波节位置A对应的位置。 Ring member 62 is provided at the node position A corresponding to the position of the ultrasonic vibrations. 在环构件62的内部设有供抽吸对象(处理片、生物体组织片)向基端方向通过的通路部58和用于限定通路部58的内周面。 In the inner ring member 62 is provided for sucking the object (sheet processing, the living tissue sheet) passage portion 58 in the proximal direction through the inner peripheral surface and a passage defining portion 58.

[0080] 环构件62在长度轴线C方向上设置为包括第I间隔件56所处的波节位置A。 [0080] ring member 62 in the longitudinal direction of the axis C is set to the position of the wave section includes a first spacer 56 which I A. 环构件62设置在比超声波振动的四分之一波长小的预定的整个范围内。 Ring 62 disposed within the ultrasonic vibration than a quarter of the entire range of wavelengths small predetermined.

[0081] 另外,环构件62也可以构成为能够经由探头22的基端侧的开口部分57相对于探头22的内部空间进行拆装。 [0081] Further, the ring member 62 may also be configured to be open through the base end side portion 57 of the probe 22 relative to the inner space of the probe 22 is removable.

[0082] 接着,说明本实施方式的超声波处理装置11的作用。 [0082] Next, the role of the ultrasonic treatment apparatus of the present embodiment 11. 若进行输入单元16中的操作等,则向超声波振子26供给电流,超声波振子26产生超声波振动。 If the input operation unit 16, the ultrasonic transducer 26 is supplied to the current, the ultrasonic transducer 26 generates ultrasonic vibration. 然后,向探头22的探头顶端面43传递超声波振动。 Then, 43 transmitting ultrasonic vibration to the probe tip of the probe surface 22. 另外,送液单元15向生物体组织输送生理盐水等液体。 In addition, the feeding unit 15 to transport liquid such as saline living tissue. 在探头顶端面43上产生气蚀,弹性较低的生物体组织被选择性地破碎,并作为处理片(生物体组织片)被切除。 Cavitation on the surface of the probe tip 43, less elastic body tissue is selectively broken, and as a treatment sheet (living tissue sheet) is removed. 此时,探头22的波节位置A由于超声波振动的内部摩擦而成为高温。 In this case, the position of the probe 22 of the node A due to the internal friction of ultrasonic vibrations and a high temperature.

[0083] 抽吸单元14使负压作用于包括探头22的内部空间52、环构件62、空洞部34以及抽吸管35的抽吸路径,并经由开口部54对切除的抽吸对象(处理片)进行抽吸。 [0083] the negative pressure suction unit 14 acts on the probe 22 includes an internal space of 52, the ring member 62, the cavity suction path 34 and the suction tube 35 and through the opening 54 pairs of suction removal object (process tablets) suction. 抽吸对象经由探头22的内部空间52、环构件62、空洞部34、抽吸管35的内部被抽吸并回收至抽吸单元14。 The inner space of the suction probe 22 via the object 52, the ring member 62, the cavity 34, suction inside the suction pipe 35 is sucked to the suction unit 14 and recovered. 特别是在超声波振动的波节位置A附近,抽吸对象(生物体组织片、处理片)不直接接触发热的探头22的空间限定面53,而是在环构件62的内侧流动。 Especially in the vicinity of the ultrasonic vibration node position A, the suction object (living tissue sheet, disposal sheet) space is not in direct contact with the probe 22 of the heat generating surface 53 is defined, but the flow in the inner side of the ring member 62. 因此,防止了抽吸对象在超声波振动的波节位置A附近凝固于探头22的空间限定面53。 Therefore, to prevent the node position A vicinity of the object in the suction solidification ultrasonic vibrations in the space 22 of the probe surface 53 is defined.

[0085] 另外,环构件62在长度轴线C方向上设置在包括第I间隔件56所处的波节位置A、并且比超声波振动的四分之一波长小的预定的整个范围内。 [0085] In addition, the ring member 62 in the longitudinal direction of the axis C is provided comprising a first spacer 56 which I nodal position A, and the ratio of the ultrasonic vibration within a quarter-wavelength of the entire range of small predetermined. 一般来说,探头22中的超声波振动的波节位置A由于由超声波振动引起的内部摩擦而成为高温。 In general, the probe 22 of the ultrasonic vibration node position A due to internal friction caused by the ultrasonic vibration and a high temperature. 根据上述结构,特别是在探头22的波节位置A能够防止以下情况的发生,即抽吸对象粘贴于探头22的空间限定面53而成为内部空间52的堵塞的起点。 According to the above structure, especially in the position of the probe node A 22 can prevent the occurrence of the following conditions, i.e., the suction space of the object adhered to the probe 22 and the surface 53 defining the inner space 52 become a starting point of blockage. 另外,能够将一体设置的第I管55和第I间隔件56所需的大小或长度轴线C方向上的长度设为最小限度,也能够削减超声波处理装置11的制造成本。 Further, it is possible to set the first one tube 55 and the length of the first I I C size or direction of the longitudinal axis of the spacer 56 desired on the set minimum, it is possible to reduce the manufacturing cost of the ultrasonic treatment apparatus 11.

[0086] 环构件62的导热性比探头22的导热性低。 [0086] ring member 62 is lower than the thermal conductivity thermal conductivity probe 22. 根据该结构,探头22侧的热量难以向一体设置的第I管55和第I间隔件56传递,能够防止处理片附着于第I管55的内表面。 According to this structure, the heat is difficult to set the probe 22 side to integrally I of tube 55 and the spacer 56 passes the first I, disposal sheet can be prevented from adhering to the inner surface I of the tube 55.

[0087] 环构件62的内周面的滑动性比探头22的空间限定面53的滑动性高。 [0087] slidability of the inner peripheral surface of the ring member 62 of the sliding surface 53 of the probe 22 is higher than the defined space. 根据该结构,能够防止处理片附着于一体设置的第I管55和第I间隔件56的内表面,从而能够防止在第I管55的内侧产生堵塞的起点。 According to this structure, it is possible to prevent the disposal sheet is attached integrally provided in the first tube 55 and I I the inner surface 56 of the spacer can be prevented at the starting point of the first inner tube 55 to produce I clogging.

[0088] 另外,在图12中,在探头22的空间限定面53与环构件62的端部之间,在供处理片流动的流路上产生了台阶,但是如图13所示,为了消除该台阶,也可以在探头22的空间限定面53上设置凹坑部65,并在该凹坑部65的内侧配置环构件62(第4实施方式的第I变形例)。 [0088] Further, in FIG. 12, the probe 22 in a space defined between the surface 53 and the end portion of the ring member 62, at a flow sheet for processing to produce a stepped path, but shown in Figure 13, in order to eliminate the steps to be defined in the pocket portion 65 provided on the surface 53 of the probe 22 in space, and the inside of the pocket portion 65 of ring member 62 (Section I, a modified example of the fourth embodiment). 或者,如图14所示,环构件62也可以以随着靠近长度轴线C方向的端部而使环构件62的内径(内侧的空洞部分的直径)变大的方式使环构件62的端面倾斜(第4实施方式的第2变形例)。 Alternatively, as illustrated, the ring member 62 may be in the inner diameter as the end portions 62 leaving the ring member near the longitudinal axis C direction (the inside diameter of the hollow portion) becomes large in a way that the end face of the ring member 62 is inclined 14 (second modification of the fourth embodiment). 由此,在探头22的空间限定面53与环构件62的端部之间的交界处,难以滞留处理片,从而能够有效地防止该部分成为堵塞的起点。 Thus, in the space 22 is defined at the junction of the probe end surface 53 and the ring member 62 between the retention is difficult to handle sheet, it is possible to effectively prevent the clogging of the starting point of the portion.

[0089] 另外,环构件62的材质并不限定于PTFE,也可以是其他种类的合成树脂(例如,橡胶、其他树脂材料等)。 [0089] In addition, the material of the ring member 62 is not limited to PTFE, it may also be other types of synthetic resins (e.g., rubber, other resin materials, etc.). 在这种情况下,为了确保环构件62的空间限定面53的低摩擦性(滑动性),也可以对空间限定面53实施表面处理。 In this case, in order to ensure the space ring member 62 defines a low frictional resistance (sliding resistance) surface 53 to be limited to the space 53 faces a surface treatment. 作为表面处理的例子,可列举氟树脂涂敷等涂敷、研磨处理等。 Examples of surface treatment include coating fluorine resin coating, etc., the grinding treatment.

[0090] 本发明并不限定于上述实施方式,在不脱离其主旨的范围内能够适当地进行变形实施。 [0090] The present invention is not limited to the embodiments described above without departing from the scope thereof can be appropriately modified embodiment. 另外,也能够组合上述各个实施方式的超声波处理装置11来构成一个超声波处理装置11。 Further ultrasonic treatment apparatus, it is possible combinations of the above embodiments 11 to 11 constitute an ultrasonic treatment apparatus.
